Twitter co-founder Biz Stone announced on Tuesday that he returning to the company in an unspecified role.

"My top focus will be to guide the company culture, that energy, that feeling," Stone said in a blog post, adding he would not be replacing anyone at Twitter when he joins the company in a couple of weeks.

Stone said that Twitter co-founder and current CEO Jack Dorsey asked him to come back to work at the company. "Excited to have Biz's energy and heart back at Twitter! #BizIsBack," Dorsey tweeted on Tuesday.

Stone is one of the co-founders of Twitter along with Dorsey, Ev Williams and Noah Glass. He quit Twitter in 2011 to co-found online publishing platform Medium and search engine company Jelly, which was sold to Pinterest in March this year.

"The (Pinterest) deal did not require me to work at the company we sold to, but I'm the type of person who has to keep working," Stone said.

Stone returns to Twitter at a time when the company is doubling down in its efforts to boost user growth. Last month, Twitter posted its strongest growth in monthly users in more than a year. The average monthly active users increased 6% to 328 million in the first quarter of 2017 from a year earlier.
